Description

Technical Field

[0001] The invention relates to the technical field of coal transportation, and in particular to an underground rail transportation device for coal. Background Art

[0002] In coal mining, the coal or waste slag mined from the coal mine will be transported by rail mine cars. The mine car is a special tool for rail transportation in the mine. In order to adapt to the narrow conditions of the underground tunnel, the outer size is compact. Usually, a winch or other driving source is used to pull the mine car to move. The mine car needs to be filled with heavy materials for transportation. Its running stability is also closely related to the track. The safety of mine car transportation is very important. Once a rollover occurs, it is easy to cause injuries. The current coal underground rail transportation device is not convenient for real-time monitoring of the flatness of the transportation track. The track is in the humid underground water seepage environment and the mine car moves for a long time, which is easy to be concave locally. It usually relies on manual inspection, which is easy to miss and cause the mine car rollover accident. At the same time, due to factors such as the long-term use of the track and the reduced accuracy of the wheelset, the mine car wheel set is prone to derailment accidents, which is not convenient for auxiliary return after the mine car derails. It is necessary to unload the materials and carry and pull them manually. Manual operation has great safety hazards, and the protection effect is not good when loading goods. Coal ore materials are easily spilled during transportation. Summary of the invention

[0039] In the embodiment of the present disclosure, the derailment reset member 4 includes: a supporting hydraulic cylinder 401 and a sliding plug-in strip 402. Four supporting hydraulic cylinders 401 are fixedly installed on the transport frame 101; the four supporting hydraulic cylinders 401 are grouped in pairs, and the output shafts of the two groups of supporting hydraulic cylinders 401 are respectively fixedly installed with sliding plug-in strips 402; the bottom sides of the two sliding plug-in strips 402 are inclined structures respectively; the four supporting hydraulic cylinders 401 are used to drive the transport frame 101 to rise; the track positioning part 5 includes: a track support plate 501 and a plug-in guide block 5011 and a positioning strip 5012, and two plug-in strips 5012 are fixedly installed at the bottom of the track support plate 501 The guide block 5011 is connected, and the inner sides of the two plug-in guide blocks 5011 are inclined structures respectively; the two plug-in guide blocks 5011 are used to limit the track; two positioning bars 5012 are fixedly installed on the track support plate 501; the inner sides of the two positioning bars 5012 are respectively provided with "V"-shaped grooves; the "V"-shaped grooves on the positioning bars 5012 are used to fit the sliding plug-in bar 402; the track positioning part 5 also includes: positioning bolts 502, two positioning bolts 502 are provided, and the two positioning bolts 502 are respectively threadedly connected to the positioning bar 5012; the ends of the two positioning bolts 502 are respectively plugged into the sliding plug-in bar 402; the positioning bolts A hand wheel is provided on 502, and the track positioning part 5 is used in conjunction with the derailment reset part 4, so that the structure can be quickly controlled to return to its original position when derailed, and the reset after derailment is more efficient.

By utilizing the "V"-shaped groove on the inner side of the positioning strip 5012 and the role of the inclined surface guiding, in conjunction with the inclined surface structure on both sides of the bottom of the sliding plug-in strip 402, the positioning can be quickly plugged in and positioned, and To return and correct the track wheel set 102, the supporting hydraulic cylinder 401 drives the sliding plug-in strip 402 to move downward. As the sliding plug-in strip 402 moves downward, it contacts the "V"-shaped groove on the positioning strip 5012, and the supporting hydraulic cylinder 401 drives the transport frame 101 to move upward as a whole. At this time, under the guidance of the "V"-shaped groove on the positioning strip 5012, as the output shaft of the supporting hydraulic cylinder 401 extends out of the support, the two sliding plug-in strips 402 will slide to the middle of the "V"-shaped groove on the positioning strip 5012 under the action of gravity for positioning. At this time, the track wheel set 102 is aligned with the track, and the return drive work is performed, which is automatically controlled and safer.

[0040] Embodiment 2, on the basis of embodiment 1, the transport control unit 6 comprises: a transport material box 601, a positioning shaft 602 and a reset spring 603, the transport material box 601 is fixedly mounted on the transport frame 101; two positioning shafts 602 are slidably inserted on the transport material box 601, and the two positioning shafts 602 are respectively provided with handles; the two positioning shafts 602 are respectively sleeved with reset springs 603; the two reset springs 603 are respectively connected between the handles on the positioning shafts 602 and the transport material box 601; the two positioning shafts 602 are respectively used for positioning There are two feed control parts 7; the feed control part 7 includes: a feed sliding plate 701 and a movable telescopic shaft 702, and three movable telescopic shafts 702 are fixedly installed on the feed sliding plate 701; the feed sliding plate 701 slides to fit the transport material box 601; the three movable telescopic shafts 702 are respectively slidably inserted into the side walls of the transport material box 601; a positioning hole is provided on the side of the feed sliding plate 701; the positioning hole provided on the side of the feed sliding plate 701 corresponds to the positioning shaft 602; the feed control part 7 also includes: a combined spring 703 and an opening and closing inclined panel 704 , there are three merging springs 703, and the three merging springs 703 are respectively sleeved on the three movable telescopic shafts 702; the three merging springs 703 are respectively located between the transport material box 601 and the feed sliding plate 701; an opening and closing inclined plate 704 is fixedly installed on the feed sliding plate 701; the opening and closing inclined plate 704 is installed obliquely, and the feed control part 7 is adopted, which can facilitate the discharge machine to directly discharge the material into the transport material box 601, and the feed sliding plate 701 with an elastic sliding structure ensures that smoke and dust are prevented from spreading during the transportation of coal and other ores, and at the same time To avoid the spillage of ore materials during transportation, the structure is more reasonable, the opening and closing inclined panel 704 can facilitate the entry of materials, and there is no need to manually control the opening of the feeding sliding plate 701 during feeding, which is safer and more convenient. When feeding, under the action of the gravity of the material, the opening and closing inclined panel 704 of the inclined surface is squeezed. At this time, the two opening and closing inclined panels 704 drive the movable telescopic shaft 702 to move to both sides respectively, which does not affect the feeding. By combining the spring 703 to squeeze the feeding sliding plate 701 and drive the opening and closing inclined panel 704 to reset, the closed dust and spillage prevention work can be carried out.

[0041] The working principle of this embodiment is as follows: first, when multiple transport frames 101 need to be connected end to end, the plug-in blocks 104 are placed inside the docking rods 105 respectively, and the rotating positioning pins 106 can be passed through the through holes on the plug-in blocks 104 for positioning. The operation is convenient and efficient. The through holes on the front plug-in blocks 104 can be connected to the winch cable for traction. When the track wheel pair 102 rolls along the track, the control roller 303 is pulled by the pressure spring 202 to fit on the track and move at the same time. If a depression appears on the front track, the control roller 303 will also move down to fit the track. At this time, if the depression is large, the detection rotating arm 301 will rotate on the detection mounting arm 201, and with the pull of the pressure spring 202, the positioning teeth 302 will be inserted into the limit teeth 103 for positioning and locking, thereby preventing the structure from continuing to move forward and causing rollover.

[0042] When the track wheel set 102 derails, the positioning bolt 502 is rotated to release the limited track support plate 501. Thanks to the liftable support hydraulic cylinder 401, the sliding plug strip 402 can be driven to the highest point first to avoid affecting the movement and adjustment of the position of the track support plate 501. The track support plate 501 can then be moved to a movable position. At this time, the track support plate 501 can be moved manually to adjust its position. The two plug-in guide blocks 5011 on the track support plate 501 are respectively attached to the two sides of the track to position the track support plate 501. At this time, the support hydraulic cylinder 401 is driven to The sliding plug-in strip 402 moves downward, and as the sliding plug-in strip 402 moves downward, it contacts the "V"-shaped groove on the positioning strip 5012, and the supporting hydraulic cylinder 401 drives the transport frame 101 to move upward as a whole. At the same time, under the guidance of the "V"-shaped groove on the positioning strip 5012, as the output shaft of the supporting hydraulic cylinder 401 extends out of the support, the two sliding plug-in strips 402 will slide to the middle of the "V"-shaped groove on the positioning strip 5012 under the action of gravity of the transport frame 101 for positioning. At this time, the track wheel set 102 is aligned with the track, and the transport frame 101 is moved upward by contracting the supporting hydraulic cylinder 401. The frame 101 will slowly move down and reset, and the track wheel set 102 will roll and fit the track. At the same time, the positioning bolt 502 can be used to pass through the positioning bar 5012 again to plug the sliding plug-in bar 402, so as to position and install the track support plate 501, which will not affect the normal movement and transportation of the transport frame 101 on the track. When feeding, the coal chute of this structure can discharge directly above the opening and closing inclined plate 704. Under the action of the gravity of the material, the opening and closing inclined plate 704 of the inclined surface is squeezed. At this time, the two opening and closing inclined plates 704 drive the movable telescopic shaft 702 to move to both sides respectively. The combined spring 703 is compressed. As the material discharge is completed, the material no longer squeezes the opening and closing inclined panel 704. At this time, the combined spring 703 can squeeze the feed sliding plate 701 to drive the opening and closing inclined panel 704 to reset for protection. When the transport material box 601 needs to take materials, the feed sliding plate 701 is pulled manually. At this time, with the pull of the reset tension spring 603, the positioning shaft 602 can be inserted into the side positioning hole of the feed sliding plate 701 for positioning. After the material is discharged, the positioning shaft 602 can be pulled again to release the positioning of the feed sliding plate 701, which is convenient for subsequent dust-proof transportation and feeding.
